Abstract

The realization and validation of a new reconfigurable metasurface high-resolution steering reflector for K-band are presented. The continuous tuning is achieved by integrating a varactor diode with each metasurface unit cell. This approach is shown in many studies, but not above Ku-band, because of implementation difficulties. This letter presents design considerations, reflection simulations, and reflection measurements of a new resonant unit cell at K-band, used for reconfigurable metasurface steering reflector. The reflection steering method and the reflection phase calibration are presented. Finally, the experimental far-field results are provided to validate the continuous beam-steering reflector performances in various frequencies at K-band, with large-angle steering, high resolution, and wide-incident-angular-range abilities.
